Abstract
The utility model relates to a brushless DC pump. The inner diameter of a stator winding of the existing DC brushless pump is limited by an impeller. In order to solve the problem, loops of a stator winding of the novel brushless DC pump are respectively wound around outer protrusions of annular silicon sheets and a magnetic driving member forming a sliding fit with an impeller shaft in the circumferential direction by sharing the same shaft is additionally arranged between the stator winding and an impeller. The magnetic driving member is composed of two concentric circular barrels which are fixed at both sides of the same circular disk and have different sizes, and the inner sides of the concentric circular barrels are respectively provided with two magnetized permanent magnets. The small concentric circular barrel is sheathed out of the impeller to form a sliding fit with the impeller in the circumferential direction, and the big concentric circular barrel is sheathed out of the stator winding to form a sliding fit with the stator winding in the circumferential direction. Compared with the existing brushless DC pump, the magnetic driving member is additionally arranged in the novel brushless DC pump and the original inner winding type is changed into an outer winding type. Due to the adoption of the technical scheme, the novel brushless DC pump has the advantages of simple structure and convenient manufacture and is widely used in various places needing miniature water pumping devices.
Description
Technical field

Background technique
Existing brush DC suction pump structure mainly is made of shell, water cover, pcb board, stator seat, stator, stainless steel impeller axle, impeller, after the energising, coil switch operating in the magnetic strength electronic component control stator, produce the magnetic force of two groups of opposed polarities, thereby have an effect with the magnet in the impeller, drive the impeller operation on the stainless steel impeller axle.The internal diameter of staor winding is subjected to the restriction of winding machine and self structure, can not be too small, too smallly then can't wind the line.Because the restriction of said structure, the internal diameter of silicon steel plate must be greater than 16mm in the stator, and this makes the production of drip pump and application be subjected to very big influence.Winding structure in simultaneously existing direct current suction pump stator adopts needs just can finish in about 10 minutes around a stator, has problems such as preparation process difficulty, efficient are low.
The content of model utility
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of applied widely, Novel DC brushless pump of being easy to make is provided.
For addressing the above problem, this Novel DC brushless pump comprises a kind of Novel DC brushless pump, comprise shell, be fixed on end cap on the shell, the impeller and the magnetic strength electronic component of stator seat, stator, impeller shaft, staor winding, band axle center hole, the impeller of wherein said band axle center hole is provided with iron, impeller shaft is packed between end cap and the shell, stator seat is packed on the shell, the impeller of band axle center hole is circumferentially sliding to be assigned on the impeller shaft, the coil of staor winding is wrapped in respectively on the projection of ring-shaped silicon steel sheet, it is characterized in that: described projection is an outer process; Be provided with the magnetic driving component of joining between its stator and the impeller with the coaxial circumferential cunning of impeller shaft, described magnetic driving component is made up of two that the are fixed in same disk both sides concentric drums that vary in size, above-mentioned concentric drum inboard is respectively equipped with two permanent magnets that magnetized, described little concentric circle casing dress and the circumferentially sliding impeller outer that is assigned in; Described big drum suit with one heart and circumferentially sliding being assigned in outside the staor winding.
So design, the action of a magnetic field that staor winding produces is rotated by magnetic driving component impeller at the magnetic driving component.Avoided the restriction of impeller to staor winding like this, reduced difficulty of processing, usage range is wide.And winding structure needs the stator that just can finish in about 10 minutes in adopting, change outer winding structure into after, only need can finish for 50 seconds, manufacturing efficiency has increased by ten times than interior winding structure.
As optimization, described permanent magnet is a glue magnetic, and its outside is provided with stiffening ring.So design is convenient to make.
If adopt the synthetic impeller bearing of copper powder to replace wear-resisting polyformaldehyde (POM) or other wear resistant plastic material bearing, can also prolong the impeller operation life-span, avoid because of the excessive generation noise that weares and teares.
After adopting technique scheme, manufacturing efficiency has increased by ten times.After improving, the silicon steel plate internal diameter is not limited by institute's impeller, has widened production and application.Existing common motor water pump, life-span is about 10,000 hours (running continuously), prove after tested, novel water pump after my company's improvement, after unloaded acceleration (harsh grade test) was turned round 2000 hours continuously under 25 ℃ of environment of normal temperature, an overhaul impeller shaft and an axle core did not have the noticeable wear phenomenon, and asking MTBF according to the accelerator formula of fan industry life test standard is 3～40,000 hours, can reach 4～5 years working life, is applicable to the various place uses that need to use small-sized water plug.
